FRANK T. MACDONALD, OF SOUTH'PENOBSCOT, MAINE.

CHIMNEY- CLEANER.

Specification of Letters Patent. Patented June 19, 1917.

Application filed July 26, 1916. Serial No. 111,389.

To all 1117mm it may concern:

Be it known that I, FRANK T. MACDON- ALD, a citizen of the United States, residing at South Penobscot, in the county of Hancock and State of Maine, have invented certain new and useful Improvements in Chimney-Uleaners, of which the following is a specification.

My invention relates to improvements in chimney cleaners.

An important object of the invention is to provide a device of the above mentioned character, which is readily adjustable for operation in chimneys of different widths or sizes.

A further object of the invention is to provide means for angularly adjusting the cleaning or scraping element so that the device may be operated more efficiently.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

l igure l is a plan view of apparatus embodying the invention,

Fig. 2 is a detail section through a joint for sections of the handle,

Fig. 3 is a side elevation of the apparatus, parts being broken away,

Fig. 4: is an end elevation of the same,

Fig. 5 is an elevation of the adjustable joint between the cleaning element or scraping blade and the body portion of the de vice,

Fig. 6 is a detail section taken on line 66 of Fig. 3, and,

Fig. 7 is a similar view taken on line 77 of Fig. 3.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates a bar or member constituting the body portion of this device. This bar is provided at its forward end with an enlarged head 11, provided with a plurality of spaced openings 12. The head 11 contacts with a co-acting head 13, having a pin or stud 14 rigidly secured thereto and adapted for insertion within a selected opening 12. The

heads 11 and 13 are pivotally connected by means of a clamping bolt 15 passing through centrally arranged apertures therein and carrylng a wlnged nut 16.

The head 13 has a shank 17 preferably formed integral therewith and this shank is rigidly secured to a cleaning element or scraping blade 18, preferably of the shape shown. From the foregoing description it is obvious that the blade 18 may be angularly adjusted with respect tothe body portion 1 0 and locked in adjustment at the de sired angular position. i

The numeral 19 designates a preferably longitudinally curved compression element, the rear end of which is preferably forked and provided with spaced knuckles 20. These knuckles are pivotally mounted upon a transverse bolt or pivot member 21, passing through an opening in the bar or body portion 10, as shown. The function of the pressure member 19 is to contact with one side of the chimney and thus retain the blade 18 in proper contact with the opposite side thereof.

Adjustable yielding means are provided to move the pressure member or blade 19 outwardly with respect to the bar 10, comprising a U-shaped carriage 22, the ends of which extend outwardly beyond the bar 10. These ends are apertured for the reception of a bolt 23 or the like, adapted to fit in a selected notch 24. Arranged within the carriage 22 is a clamping member or block 25, contacting with the bar 10, and adapted for engagement with the inner end of a clamping screw 26, having screw-threaded engagement within an opening formed in the end of the carriage 22. From the foregoing description, it is obvious that by proper manip ulation of the clamping screw 26 the carriage 22 may be longitudinally adjusted with respect to the bar 10, the bolt 23 inserted within a selected notch 24, and the clamping screw 26 screwed up to bind the car riage to the bar 10, with the bolt 23 locked within thenotch. It is thus apparent that this carriage is longitudinally adjustable upon the bar 10 and means are provided to lock it in adjustment at desired longitudinal positions.

The numeral 27 designates a spring, the arms of which are coiled about the bolt 23 with its end 28 extending forwardly of the pivot 23 and contacting with the bar 10. Pivotally connected with the outer end of the spring 27 is a roller 29, contacting with the inner side of the pressure member 19. It is apparent that the spring 27 will function to move the blade 18 outwardly and that the extent of this outward movement may be regulated or adjusted by moving the carriage 22 toward or away from the pivot 21 0f the member 19. It is thus apparent that the device is adapted for use in chimneys of different widths.

The rear end of the bar 10 is preferably tapered as shown at 30, and this tapered end fits within an opening or socket 31, within a handle section 32.

The numeral 33 designates a. co-acting handle section, carrying a book 34:, adapted to detachably engage an eye 35, carried by the handle section A slidable sleeve 36 is carried by the handle section 33 and is adapted to be moved into engagement with the end of the handle section 32, while engaging the end of the handle section 33, thus serving to rigidly hold the handle sections against lateral movement with respect to each other, while the co-acting hook and eye prevent the relative longitudinal movement thereof. It is obvious that these handle sections may be made in any suitable length and there may be any suitable number of them.

In use, the carriage 22 is adjusted longitudinally of the bar 10, so that the spring 27 will retain the member 19 away from the bar 10, at a suitable distance, depending upon the width of the chimney to be cleaned. The member 19 engages one side of the chimney while the blade 18 the opposite side. By proper movement of the device, the blade will scrape the side of the chimney and remove deposits therefrom. The blade 18 may be angularly adjusted as hereinabove stated.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, 1 claim:

1. A chimney cleaner of the character described, comprising a body portion, a cleaning element secured to the forward end thereof, a pressure member pivotally connected with the body portion and adapted to swing toward and away from the same, yielding means carried by the body portion and serving to move the pressure member outwardly, and adjusting means arranged inwardly of the pressure member and out of contact therewith and serving to regulate the action of the yielding means so that such yielding means is capable of swinging the pressure member outwardly for a greater distance.

2. A chimney cleaner of the character clescribed, comprising a body portion, a clean ing element means for angularly adj ustaljily connecting the cleaning element with the forward end of the body portion, a pressure member pivotally connected with the body portion and adapted to swing tmrard and away from the same, yielding means carried by said body portion and serving to move the pressure member outwardly, and adjusting means arranged inwardly of the pressure member and out of contact therewith and serving to regulate the action of the yielding means so that such yielding means is capable of swinging t 1e pressure member outwardly for a greater distance.

3. A chimney cleanea' of the cl'iaracter described, comprising a body portion, a cleaning element secured to the forward end thereof, a pressure member connected with the body portion and. movable laterally toward and away from the same, a carriage slidably mounted upon the body portion to be adjusted longitudinally thereof, and a yielding element secured to the carria and contacting with the pressure meml'ier.

4. A chimney cleaner of the character described, comprising a body portion, a cleaning element secured to the forward end thereof, a pressure member connected with the body portion and movable laterally to ward and away from the same, and yielding means longitudinally adjustably mounted upon the body portion to be shifted longitudinally thereof and adapted to act upon the pressure member at different distances from its pivot.

In testimony whereof I allix my signature in presence of two witnesses.
